The CAPTURE Study: Validating a Unique COPD Case Finding Tool in Primary Care (Aim 2)

This is a prospective, multi-center qualitative study engaging clinical staff at all levels
from primary care practices serving US patient populations of differing gender, racial,
ethnic, urban/rural and socio-economic blends.

The CAPTURE tool consists of a 5-item self-administered questionnaire and selected use of
peak expiratory flow (PEF) measurement, designed to identify clinically significant COPD.

This study will assess, using the RE-AIM approach, how real-word primary care practices might
potentially use CAPTURE to: a) identify target populations (Reach); b) appraise optimal
targeted respiratory history and symptoms consistent with clinically significant COPD
(Effectiveness); c) integrate into practice workflow (Adoption); d) deliver changes and
improvements to COPD care within the scope of real-world clinical practice (Implementation);
and e) persist in use and quality over time (Maintenance).

Approximately 150 clinicians from 10 participating primary care practices will undergo
detailed implementation investigation of the CAPTURE case finding model for clinically
significant COPD. In addition, 200 enrolled participants will complete a 10-minute written
CAPTURE opinion survey.

Using the RE-AIM framework and consistent phased qualitative analyses, this aim ascertains
reach, impact, adoption, implementation and maintenance primary care feasibility
recommendation characteristics of CAPTURE via pooled assessment of prescriber clinical staff,
non-prescriber clinical staff, CAPTURE-eligible patients and local PBRN clinical quality
improvement expertise from 10 primary care practices across 5 US regions.
